Center for Electron Microscopy and Analysis

The Center for Electron Microscopy and Analysis (CEMAS) is the preeminent materials characterization hub for business and academia. CEMAS was established to provide a world-class environment for the teaching and practice of advanced microscopy across all scientific disciplines. The point of difference lies in the multidisciplinary approach taken to drive synergy, amplify characterization capabilities, and challenge what is possible in analytical electron microscopy. With one of the largest concentrations of electron and ion beam microscopy instruments for materials characterization, CEMAS strives to be the most advanced microscopy facility in the world.


CEMAS was partly funded by IMR’s ORSP award – Technology Enabling and Emergent Materials (TEEM), which also provided the position filled by David McComb, who is the CEMAS director and an IMR associate director. CEMAS facilitates electron microscopy application to an incredible breadth of science — from biomaterials and bio-inspired materials to nanoelectronics, energy materials, advanced structural materials, and medicine. Capabilities include scanning electron microscopy (SEM), focused ion beam microscopy (FIB), transmission electron microscopy (TEM), X-ray diffraction (XRD), micro-computed tomography (micro-CT), and cryo-electron microscopy (cryo-EM). Recently installed equipment includes a Thermo Scientific Themis Z S/TEM and Thermo Scientific Glacios Cryo-TEM. CEMAS offers a full-service, expertly designed environment for researchers to execute their entire microscopy and analysis program. During FY20, CEMAS provided research services totaling more than $1.12M and supported 278 users from 134 research groups.
